T0 ALL WHOM ITMAY CONCERN:

Be it known .that I1, ALFRED FAUVIN JALOUREAU, ot Paris, in the Empire of France, manufacturer, have invented certain new and useful Improvements in the Manufacture of 'l'clegraphic Cables, and in the'apparatus connected therewith; and Ido hereby declaro that the following vis a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters marked thereon; that is to say-"- This invention consists, V

First, in an improved method of forming telcgraphic cables by the application of successive layers of bitu-, men, separated and maintained by spiral bands of bituminized paper, and consolidated by one or several coverings of bituminized corda-ge` the whole encased, when necessary, bynietal wire, and an outer coating of bitumen.- Y

Second, in the combination of'machineryby aid oi. which Vthe processY of manufacture muy be executed with facility, certainty, and economy.

The protection `and insulation of the condueting-wires comprise the following operations:

First. Coiling of bituminized cord on the wires, and formation of the cable.

Second. Transit of thev cables thus prepared through baths of het bitumen, to form the-successive layers, which are separated und maintainedbydoubte envelopes-of bitnminizcd paper.-

Third. Formationof a protective envelope of bituminized cord or twine'.

Fourth, Application, according to circumstances, of a covering of metallic wire.

Fifth. ,Applicationof an external coat-ing ofbitumen, combined with sand.

Plate 1, Figure' '1, of the accompanying drawings, is an elevation ofthe machinery employed for the mannA facture of the cable. i

Figure 2 is a pian of the same. l

Plater, Figure 1, is a section throughthe line 1-2, iig. 1, plate 1.

Figure 2 is e. section throughthe line 3-4, iig. 1, plate 1.

Figure 3 is a section through the line 5-6, iig. 1, plate 1,

Figure 4 is a longitudinal section of the cable,- represcnting the distribution of thcsuecessive protective envelopes. Y v

Figure 5 reproduces, in' cross=sectiens, the different stages oi' formation of the cable, corresponding with the longitudinal section, g. 4.

Figure 6 is an external view of the cable, with its casing of iron wire, (in bluc,) the coating of bitumen ucing removed. Y r

Figure 7 is a. cross-section of the wooden conduits used in subterrane'ous lines passing through towns.

A is a drum, carrying the conducting-wire or core, which passes from thence throughthe gorges of two pulleys, B Bf, by which it is tightly'pressed. These pulleys, by which the wire is regularly carried forward, receive their motion" from the main shaft P, through an endless screw, M, mounted thereon, and. l:acting on a toothed wheel fixed on the axle of the lower pulley, B.v The upper pulley, B', is so arranged as to press the wire. The latter then passes through a hole pierced in the axle of thegear-whccl I); from thence into thc'guidesupport S, near which it is surrounded by two bituminized twlnes, delivered by the bobbins C C, the latter' rotating round the wire received from thewheel on which they are mounted. Qn leaving these bobbins, the4 'twines pass into two small cylindrical guides, 1' r, fixed on the guide s, which followsrthc rotation of the wheelV b. 'lhesc two guides-are se arranged as to produce the regular ceiling of the two twines ata certain degree ofl inclination. i

1n passing over the' boiler E, which is charged with melted bitumen, (maintained in fusion by steam from the pipe L or otherwise,) the twine-covered wire comes in contaetwith the cylinder I, which, rotating partly immersed in the melted bitumen, carries over by adherence a pellicle of the latter. The bitumen thus forms en the cable a layer, .the thickness of which is regulated by a metallic cone, p, passing through it, andsceureil to the side of the vesseiE. From thence the cable passes through the hole pierced in the axleof the wheel'b. and receives a double envelope of bituminizcd paper from the revolving bobbinsD D. The rotation et' these bobbins is'produecd by the -whccl b1, on which they are mounted. l

'lllebandso bitnminized paper delivered bythe bobbins D D pass into -the openings ff, cut in the guide T, set on and -revolving with the wheel b. These openings are so arranged as to compel the paper bands to coil over the cable at a certain degree of inclination, so that the axis of the external band exactly coineideswith and covers the joint-of the band beneath.

fThe.cal ,le.,;tims provided with its double envelopeotfibitnminizcd paper, passesntoasecnilbath 'of melted bitumen, El, where it receives n. new coating. It isthen again covered with a double envelope of bituminiaedv paper, delivered by the hobbins l)l Dl, similar to those just described. This operation is repeated three, four,

or more times, as may be required, by'means of the bathss'E2 E, and'bobbins D2 Dz ID3 D, so as 'to form three, four, or more layers of bitumen, separated by an equal number of envelopes of bituminizedpaper The last paper envelope being applied, the cable passes into the support R4, provided with the gear b, and with fourbob'bins, CC"Cl C', exactly similar to those marked C. It there receives a covering of bituminized twine, supplied .by the four yarns of the four bobbins C', the objcctot this covering being to protect the core of the cable from accidental injury from without. It`is then vcoated with a iinallayer offbitulnen in the vessel E3; whichla'yer is sanded in the case F.

The cable thus-prepared passes through the gorge-pulleys N G 0 X, the object of which isto stretch and rotnd it regularly, and to press into the bitumen the sand taken up from the caselli'.

The. gorge-pulley G receives its rotation from a toothed wheel mountcdon its axle, and acted on by an endless screw, M, li.\ed on the shaft I. The pulleys O X revolvewith suieientspeed to give a certain amount of polish to the cable, which from thence is wound olf on a store-drum.- The shaft P imparts motion to all the 'twine-bobbins, as also to the bituinen-distributing apparatus, through the pinions c c fr" c c, Sie., the interme diste wheels, L Z iljd d d*,.&c., acting on the wheels b'bl In ld, &e. The transmission to the bitumen-distributors is eected by flat bolts and pulleys, or by gorge-pulleys and-cords.

When a protective wire covering is required, it may be applied to the cable by devices similar to those above described, a. final coating of bitumen (or even of twine and bitumen, if necessary) being passed-over all, to protect the metal from the action of. the air or water. In this case, the wire coils shouldbc applied in a contraryV .w direction'to that of thc twine envelopes beneath.

The machinery above described may be modified by causingA the conducting-wires .toirevolveJ the twine .and

'paper bobbins being kept stationary.` To this end, the drum A, and the pulleys N-br O X, should'be mounted on platforms, rotated by a driving-shaft, the forward movement of the wires being eected by pulleys, regulated by a stationary screw, mounted on the support of the drum. The advantage of this arrangement lies in the increased facility-cl` controlling tbe progresso? the work, and of changing the bobbinsl as required, without In the operations-above described, either vegetable or mineral bitumens may-bc employed, the temperature nt which they are melted being `varied according to the degree of iiuidity required. The inner layers should beformcd of more supple material than the exterior coatings, the bitumen being in .all cases suihciently pure to linsure perfect insulation. If so desired, the twisted co'rd or twine may be replaced by untwisted yarn, or other suitable textile material. In certain cases, such as town lines, thc-cable may bc enclosed in creosoted or bituminizcd wooden condn'its,'as represented in tbc section, iig. 7, or in metal, earthenware, or bituminized paper tubes.

Having thus described the nature of the saidimprovements, and the manner of carrying them into effect,

v I would have it understood that I do not confine myself' to the precise details above laid down, as these may obviously be modified according to circumstances,without deviating from the principles or main features ot the invention; but

What I claim, anddesire to secure by Letters Patong, :s

1.' The-improvedm'cthod of forming telegraphic cables by application of--e'ueeeesivo-luyers et` bitemerr,

separated and maintained by spiral bands of bitumin'izcdpapcr, and consolidated by coils of bituminized twine vor yarn, the whole protected, when nccessaxypby'an router covering of metallic wire, substantially. as above specified.

2. The improvedl combination ofmachinery, by aid of which the manufacture cf the said cable may be eieeted with facility, certainty, and economy, substantially as herein set forth, and shown in thegures of the accompanying drawings.' A F JALOUREAU Witnesses L. MUzAnD'r, E. MAnrlNsr
